I'm seeing this ad, that a guy looked at a trousers, and said "four pleats". Then he asked another guy,
"how many pleats does this music have?"
Apparently the other guy never heard of such expression before, so he asked "what?". Then the first guy answered himself, "four".
This is the first time I ever heard of the word "pleat". I looked it up, and found it is only used to describe clothing, not for music.
I know the ad is trying to be creative, but don't know what the point it is trying to make by using the word "pleat".
Also, what it is correctly called, for music of 2/4, 3/4, 4/4, etc?
